The Schorth ralleye is made to fit a bunch of different cars. I'd maybe call HMS Motorsport to get the details on why it would be good or bad.

Unfortunately the Rallye is not Hans Device compatible; so I'm more interested in the Quick Fit Pro which is Hans compatible but also car specific.

BTW it is Rallye not Ralleye - sorry, hate to be that guy but I've seen you misspell it like a dozen times in this thread

I talked to Bimmerworld and they basically said that this kind of product (I also asked about Quick Fit Pro about caliper brass guides) will become available as the cars get older and more and more people track them...

Now can someone point me to the thinnest pair of gloves? My hands are a bit sweaty so gloves are probably a good idea but I'd like to retain the "naked hands" feel as much as possible. No dirty jokes please...

Try these gloves -- very thin -- I have used them for the last year on the track and like them...

I'll hit up HMS and Schroth directly and report back.

Lol...no problem.

I've been using the rallye with my Hans and it works. The shoulder straps aren't as well position on the front part though.

Can someone that has installed the Mini R55 harness in their E92 please post some pics of the bend I've read about, as well as details of all the mounting locations??? If these really work, I'd love to get one. Thanks in advance guys.

So has anyone using the R55 harness had any issues? I'm getting a decent amount of grief from people on another forum, mainly about how using a non approved harness will end up being more dangerous than just the stock seatbelt. I like being held in the seat, but the idea of a broken back does kinda suck. Thoughts?? Comments?? I appreciate it.

What particularly are they saying is the issue?

If the issue is seat back strength...then how do the OEM restraints pass NHTSA test...or whoever does the tests? AFAIK, that's the only component that is unique to the car fitment. Other than that, every Schroth quick fit uses the OEM tensioners and seat belt mounting points. I think if you run BMWCCA events you might not pass tech. OK, just use the 3pts for that day. Otherwise, I think the 4pts are fine.

That is apparently the issue. See the quote below from Schroth's website. The OEM restraints pass because the shoulder belts don't run down into the rear of the car.

Shoulder Belt Routing (applies to all restraint types)

· Shoulder belts must run from the shoulders horizontally or down, at no more than a 20° angle.

· In cases where the shoulder belts must be routed down to the chassis floor, support by a roll cage bar or harness guide at the appropriate height is essential to establish the horizontal shoulder strap routing off the shoulder/HANS®. Most racing seats are not designed and tested to carry shoulder belt crash loads from downward installation. Severe injury or death could result. A 45° downward shoulder belt installation is possible with seats that SCHROTH has positively tested to take a load measured during a 50 kph [31 mph] and 28 G impact with a 75 kg (175 lb) dummy. Refer to the list of SCHROTH approved racing seats in section “About Seats”. WARNING: 45° downward shoulder belt installation is not recommended with HANS®.

How is there a substantially different impact from an installation to the rear of the car? If the seat back fails you'll fall back, with an Oem belt or other. I guess I'm not visualizing this. Can someone explain?

I installed the harness last year but didn't get out, so look forward to using it in April.

Schroth has two lines of harnesses. One are standard 2"/3" harnesses designed to be used with a harness bar and bolted to the chassis. The other line, the tuning line, are designed to be integrated with the OEM restraint system.

Make sure that you are taking those quotes and applying them to the right product.

It clearly states for all applications in parentheses. And I wasn't talking about the Pro. Just the regular quick fit.

As far as the dangers with the belt being routed downward, it has to do with how the force of an impact is distributed across your body and the harness. If routed incorrectly or at an unapproved angle, the shoulder belts will basically compress, and break, your spine.

That's how it was explained to me anyway.

Yeah, the belt must not be angled sharper than 45 degrees downward behind the seat for a Rallye4. Otherwise, you need a Rallye3. I don't think you'll run into that issue with the E9X. The only question is seatback strength.

My take is you're a safer driver when you aren't bracing yourself and diverting energy to keeping yourself in place. While locking the seatbelts and CG locks are OK, I still think the Rallye4 is a better alternative. Personally, I'm willing to assume that the seat back strength is adequate. Nothing leads me to believe otherwise.

I have read the whole thread, and was still wondering: Is anyone using these for DD street driving? Would it be unsafe to do so?
I don't see myself running a HAN device any time soon (I've done HPDE but haven't tracked yet), is there still a reason to get the pro version, and does the non-pro version have any benefits/convenience over the pro?

There is no reason why you couldn't use for DD. I don't personally. At the track, I just clip both belts in anyway.

I have a Rallye 3 installed, and it does a good job of keeping you bolted down, but is significantly much more difficult to install as the rear parcel shelf needs to come out. However, there is no question about the restraint angle of the tail straps as it goes straight back. Schroth recommended the Rallye 3 in lieu of seat back strength results being available for E90 seats.

It's not unsafe, just uncomfortable for DD. you're belted in so tight that you cannot reach the door handle if the door fully opens, or reach in th back seat for a wallet, or in the glovebox etc.

And if you don't plan to ever run a HANS device in this car, then you simply don't need that version.

I feel that in the order of importance of all the mods I did for the track, brake pads come first, harness comes second and wheels/tires third.

Got confirmation today that this product is close to arrival. Taking preorders shortly and should see first units within next month or 2. Talked to rep about the lap belt issue not tightening enough and he thought there wouldn't be any more adjusment in the M3 belt so don't know if switching makes any sense.
